STEAM-JOINT.

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed August 11,1906. Serial No. 330.152.

To all whom it may concern:

Be it known that I, GUY R. PRIDE, a citizen of the United States,residing at Jacksonville, in the county of Duval, State of Florida, haveinvented new and useful Imrovements in Steam-Joints, of which thefollowing is a specification.

My invention relates to forming temporary vapor-tight joints without theuse of fastening devices, and is particularly applicable to deviceswherein one vessel is to be removably set within another and is ofsuflicient weight to form, in conjunction with my improved construction,a vapor-tight joint that will permit of steam or other vapor beingintroduced through the outer vessel into the inner vessel. This object Iaccomplish in the manner and by the means hereinafter described andclaimed, reference being had to the accompanying drawings, in whichFigure 1 is an elevation of my improved construction. Fig. 2 is acentral vertical sectional view taken at a right angle to Fig. 1.

Similar numerals of reference denote corresponding parts in the twoviews.

In the said drawings the referencenu meral 1 denotes a steam-supply pipetapped into an elbow 2, having a shoulder 3 on its outer surface, asshown. Tapped into the other end of said elbow is a pipe 4, that passesmovably through a stuffing-box formed by a casting 5, having ascrew-threaded ring 6 engaging the same, between which is located apacking 7. Said ring is boltedto a casing or vessel 8, through anaperture in which it and the pipe 4 pass, while also bolted to saidring, by means of bolts 9, is a yoke 10, passing around the elbow 2 andhaving .a set-screw 11, controlled by a hand-wheel 12, engaging theshoulder 3 on said elbow, whereby said pipe 4 may be adjusted in itsstufiing-boX. The inner end of said pipe 4 is provided with a collar 13,having angular sides and terminating in a comparatively narrow edge 14.

The under side of the vessel 15,into which the steam or other vapor isto be introduced, is recessed at 16, its sides lying parallel with theangular sides of the collar 13, and has located in said recess anannular packing-ring 17, of comparatively large area, with which theedge 14 of collar 13 is intended to contact. Said vessel 15 is aperturedcentrally with respect to the recess 16 and has bolted to its other sidea fitting 18, receiving a steamdistributing pipe 19, screwed thereinto.

From the above description the operation of my improved constructionwill be understood to be as follows: To form the joint, the hand-wheel12 is first screwed downwardly in its yoke 10 to its lowermost position,so that when the vessel 15 is lowered into position in the casing 8 andits packing 17 contacts with collar 13 of pipe 4 the latter is free toyielddownwardly in its stuffingboX under the weight of said vessel 15and its contents. The parts being in this position, the hand-wheel 12may be manipulated to force the pipe 4 upwardly in its stu'lfingboX toseat tightly against packing-ring 17, whereby a perfectly steam-tightjoint will be provided. I form the packing-ring 17 of comparativelylarge area in order to compensate for any slight lateral variation ofthe position of vessel 15 in the casing 8.

In an application filed by me of even date herewith, Serial No. 330,151,I have illustrated my improved construction as applied to an apparatusfor extracting turpentine and other products from wood, to which it isparticularly applicable, though it will be evident that said device isequally applicable to many other forms of apparatus.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An apparatus of the character described, embodying an outer casing, asteam.- pipe passing through said casing and adjustable therein, aninner vessel adapted to seat in said outer casing and having apackingring adapted to contact with said steam-pipe, and asteam-distributing pipe within said inner vessel registering with saidouter-casing steam-pipe through said packing-ring.

2. An apparatus of the character described, embodying an outer casing, astuding-box therein, a steam-pipe adjustable in said stufling-box, aninner vessel adapted to seat in said outer casing and having apacking-ring of comparatively broad area adapted to contact with saidsteam-pipe in any position that said inner vessel may assume in saidouter casing, and a steam-distributing pipe within said inner vesselregistering with said outer-casing steam-pipe through said packing-ring.

3. An apparatus of the character described, embodying an outer casing, astuffing-boX therein, a steam-pipe adjustable in said stuffing-box, aninner vessel adapted to seat in said outer casing and having apacking-ring adapted to contact with said steampipe, and asteam-distributing pipe Within said inner vessel registering with saidoutercasing steam-pipe through said packing-ring; 4. An apparatus of thecharacter described, embodying an outer casing, a studing-boX therein, asteam-pipe movable in said stufling-box, a yoke attached to said outercasing and surrounding said steampipe, a set-screw in said yoke engagingsaid steam-pipe to regulate its movement in said stufiing-box, an innervessel adapted to seat in said outer casing and having a packingringadapted to contact With said steam pipe, and a steam-distributing pipeWithin said inner vessel registering with said outer-casing steam-pipethrough said packing-ring.

5. An apparatus of the character described, embodying an outer casing, asteampipe passing through said casing and adjustable therein and havinga narrow annular seat at its inner end, an inner vessel adapted Intestimony whereof I have hereunto set 0 my hand in the presence of twosubscribing Witnesses.
